The largest rectangle inscribed in a circle would be the inscribed square. You can calculate the area of the square by the fact that its diagonal is the diameter of the circle.
Find the dimensions of the rectangle of largest area that can be inscribed in a circle of radius a in C programming
A circle of radius, r, has area pi r2. The largest square inside it is made up of four isosceles triangles whose equal sides are of length, r, and thus has area 1/2 r2. Thus the area of the contained square is 2 r2.
Approximately 5.66x5.66 in. Or root32 x root32
Calculate the area of a rectangle and of the semicircle separately, then add.
The largest rectangle would be a square. If the circle has radius a, the diameter is 2a. This diameter would also be the diameter of a square of side length b. Using the Pythagorean theorem, b2 + b2 = (2a)2. 2b2 = 4a2 b2 = 2a2 b = √(2a2) or a√2 = the length of the sides of the square The area of a square of side length b is therefore (√(2a2))2 = 2a2 which is the largest area for a rectangle inscribed in a circle of radius a.
add the perimeter of the rectangle, minus the side that'c covered by the semi circle. then, find the circumference of the semi circle [diameter x pi, divided by 2] and addd them together
Area of circle = pi*212 = 1385.44236 square cm Area of rectangle = 1385.44236 square cm Lenght of rectangle = 1385.44236/18 = 76.96902 cm Perimeter of rectangle = 2(76.96902)+2(18) = 189.93804 cm
find the circumference of the circle and multiply it by the height of the cylinder
If you notice there are four rectangles in the dark. Each rectangle contains a circle, find the rectangle that contains the circle that you are at and then click until you have the right pattern.
It depends on what you are trying to find the area of. The area of a rectangle is calculated by multiplying the length of the rectangle times the width of the rectangle. The area of a circle is calculated by multiplying pi times the radius of the circle squared. See the Related Links for more information on calculating area.
It'll be the largest chord of the circle.
Measure the rectangle, multiply the sides. Measure the hole, find the area. Subtract circle from rectangle.# 5x6 rectangle. 5*6 = 30 # Circle is 3 inches across, 3.14*(3/2)2 = 7.065 # 30-7.065 = 22.935
